Johnson & Johnson has said it is delaying the rollout of its coronavirus vaccine in Europe amid a US probe into rare blood clots.

The company announced the decision on Tuesday after regulators in the United States said they were recommending a “pause” in administration of the single-dose vaccine to investigate reports of potentially dangerous blood clots.
